How much will you be paying for the Samsung Galaxy S6 smartphone when it releases April 10? Likely a few dollars more than you paid for the Galaxy S5, if details from T-Mobile are accurate. The possible price of the Galaxy S6 was recently spotted within marketing material for the device.

T-Mobile is now promoting the new flagship in a giveaway. The contest rules put the Samsung Galaxy S6’s approximate retail value at $699. Those interested need only sign up with their full name, email address and phone number if they want a chance to win, but those outside the lucky few will have to shell out a few hundred dollars. Smartphones in the Samsung Galaxy S line have typically been priced between $599.99 and $649.99 off contract and between $199.99 and $249.99 with a two-year contract in the U.S. However, reports have suggested that a price increase is likely for the Galaxy S6 due to its new design, upgraded features and new services like Samsung Pay.

Other price details have hinted that the base model, 32GB Galaxy S6 could sell for about 699 euros ($772) when it launches, which could translate to $699 in the U.S. The Samsung Galaxy S5 initially sold for 650 euros ($718) in Europe and $650 in the U.S. when it launched last April.

This is the first time that a Galaxy S smartphone has had 32GB of internal storage as its base model, which could also contribute to the possible price increase of the Galaxy S6. Previous Galaxy S models started at 16GB of internal storage. The 64GB model is expected to sell for 799 euros ($882). Samsung also introduced a new storage capacity -- 128GB -- for its top-end model, which is expected to sell for 899 euros ($993).

The Galaxy S6 Edge, which Samsung announced alongside the Galaxy S6 on Sunday, should also be quite expensive, as expected. The device features a dual-curved display; the 32GB model should sell for 849 euros ($937), while the 64GB model should sell for 949 euros ($1,047) and the 128GB model for 1,049 euros ($1,440). This isn’t surprising considering that the Samsung Galaxy Note Edge sold for $950 when it launched last October.

The Samsung Galaxy S6 and Galaxy S6 Edge will be available in 20 countries when it released April 11, with availability to other markets coming later.

U.S carriers including T-Mobile, AT&T, Sprint, Verizon, U.S. Cellular and Cricket have already confirmed they will offer the Galaxy S6 and Galaxy S6 Edge.
